[ns] passing parameter from TCL to C++

[Jingwen Jin <jjin1@uiuc.edu>]

Dear all,

I'm a beginner in ns and tcl. I'm trying to create an agent called Proxy
in tcl:

	set p0 [new Agent/Proxy]
	$ns attach-agent $n0 $p0

For each proxy, I would like to associate some properties. Could somebody
please tell me how to create parameters in tcl, and later on pass that to
C++?

Specifically I want something like:
	set p0 [new Agent/Proxy("blabla")]  -- This syntax is wrong

And then use the constructor ProxyAgent::ProxyAgent("blabla") to create a
proxy agent. How should I do in this case?

Thanks a lot,

Jingwen
